In a bid to revolutionize Bangkok’s approach to waste management, the city’s latest marvel, the On Nut waste-to-energy power plant, is set to be completed by late 2026. Overseeing the ambitious endeavor is Jakkapan Phiewngam, Bangkok’s deputy governor, who recently took a tour of the site nestled in Prawet district.
Spanning an impressive 30 rai, the On Nut Waste Disposal Centre is getting its wings thanks to a colossal investment of 4.89 billion baht from New Sky Energy (Thailand). It’s a green initiative with an electrifying twist, aimed at transforming Bangkok’s burgeoning waste output into much-needed power for the city.
Construction of this monumental project kicked off on February 19 of last year. The countdown is on, with roughly 1,000 days allocated for its completion and a due date locked in for November 14, 2026. Once operational, the plant promises to tackle a hefty chunk of Bangkok’s refuse, with the capability to incinerate a staggering 1,000 tonnes of waste per day. This represents about 10% of the city’s daily mountain of garbage, which amounts to 10,000 tonnes.
The sheer magnitude of rubbish processed will churn out a mighty 35 megawatts of electricity per month, lighting up more than just the imagination of eco-conscious residents. The process is as innovative as it is efficient. Upon arrival at the On Nut facility, waste will be stored in covered zones for a brief spell of 3–5 days. This pause allows for a crucial reduction in humidity by 35%, ensuring optimal conditions for combustion.
Employing state-of-the-art combustion waste management technology, the plant will fry the waste at blistering temperatures reaching approximately 1,000°C. The heat from combustion isn’t just hot air. It artfully transforms water into steam, which in turn drives turbines to generate electricity. And while the transformation of trash into energy is jaw-dropping, the leftover residue is surprisingly modest. Only about 15–20% of the waste remains as ash, neatly collected for landfill or possible repurposing.
To further boast of its high-tech prowess, the plant will incorporate an automated computer system to steer its operations, complete with an air pollution treatment ensemble to ensure emissions are as clean as a whistle. For nearby communities, the news gets better. The plant is designed to keep those pesky pungent odours at bay—a common nuisance at traditional garbage disposal sites.
Deputy Governor Jakkapan Phiewngam proudly reports that the project has made significant strides, with completion currently standing at 28%. Concrete floors are laid, waste pits are prepped, foundations are solid, and machinery, transmission lines, and the power system are all making headway.
The Bangkok Metropolitan Administration (BMA) remains vigilant, mindful of safety protocols, and has instructed contractors to unwaveringly adhere to measures aimed at tackling the insidious PM2.5 dust problem. In a city bustling with vibrant ambitions, the On Nut plant stands out, daring to tackle waste—and perceptions—one tonne at a time.
This sounds like a fantastic step towards sustainability! I’m all for turning trash into energy.
While it’s a great initiative, we need to ensure it doesn’t become an excuse for people and companies to produce more waste.
True, education on reducing waste should still be a priority, alongside developing such technologies.
I doubt this plant will make any real difference with Bangkok’s waste problem. We need more tangible solutions.
Mike, every bit helps. If it can handle 1,000 tonnes a day, that’s progress!
I agree with Mike, we should also focus on reducing waste production, not just dealing with the aftermath.
Combining reduction efforts with such projects can be a comprehensive approach.
Does anyone know if these plants are really as green as they claim? I’ve read they can still produce harmful emissions.
They have emissions treatment systems, but nothing is perfect. Regulations ensure they do their best to minimize it.
True, Joan, but we need to monitor them vigilantly to ensure they keep those standards.
What’s exciting is the potential for this model to be replicated in other emerging economies. This could change the game globally!
Exactly! Especially in countries where landfill space is limited.
I’m worried about the noise and the smell, even with measures in place. Residents deserve clean air and a peaceful environment.
I guess this is necessary, but isn’t recycling a better option than burning trash?
Recycling is great, but not all materials can be reused, and this helps tackle what’s left.
Plus, this tech has the potential to convert non-recyclables into energy, which is better than just burying them.
Does anyone know how much of the energy produced will actually be used by local communities?
Innovative projects like these are crucial, but what about the long-term health impacts on nearby communities? That’s my concern.
I’m thrilled to hear about the automated system to steer operations and handle pollution. That sounds really high-tech!
Automation sounds efficient, but doesn’t it also mean fewer jobs for people in the area?
With proper regulation and community involvement, this project could really lead Bangkok into a cleaner future.
Let’s just hope the government follows through. Promises are easy to make.
I still think more green spaces in the city would have a direct impact on our environment, more so than another industrial site.
When it comes to climate change, every action counts. This plant is a step in the right direction, but we shouldn’t stop here.
I think it’s truly commendable that this project is also addressing PM2.5 – those persistent pollutants can really affect health.
Yes, and reducing PM2.5 significantly improves quality of life for city dwellers.
After reflecting, I believe such projects should accompany increased efforts in waste management education and policies across sectors.
Absolutely, Emily! A multi-layered approach is what’s needed.
What other countries have similar success stories with waste-to-energy plants? Would love to read more examples.
